"The SI-28 appears to be a more powerful version of the AMD
Sempron-based SI-24S digital signage PC (pictured below, right),
which Ibase began shipping in March. The SI-28 supports a single-
or dual-core Athlon, or the quad-core X4 (Phenom) processor, which
can be clocked at up to 2.8GHz. Graphics are provided with the ATI
E4690 GPU (graphics processing unit), which boasts 320 stream
processor cores and 512MB of GDDR3 video memory, says Ibase. Up to
4GB of dual-channel DDR2 800MHz system memory is said to be
available via dual SODIMMs.
"Whereas the SI-24S offered two DVI video ports, which were said
to support HDMI options via expansion cables, the SI-28 comes
without four independent HDMI outputs that are claimed to support
1080p HD video. I/O includes a gigabit Ethernet port, four USB 2.0
ports, and two COM ports. Options for WiFi, 3G, or a TV tuner are
said to be available via dual PCIe minicard interfaces. A 2.5-inch
bay supports an internal hard disk drive (HDD), or a solid state
disk (SSD), says Ibase."
